 * 1. Concept: immersive chapters, taken from Amazonian textile. A painted river landscape opens the guide; the guide
 *    then reads as full-width chapters, each on its own ground (river green, clay, bone), like bands of woven cloth.
 * 2. Type: Spectral (calm book serif, real italic) for reading and titles; Fira Sans Condensed (narrow sans) for
 *    labels, navigation, tables and chapter captions.
 * 3. Palette: bone #f2ece1, river green #1f3d34, clay #8f4329, sand #d9b48f (labels on green), ink #1d211e.
 * 4. Layout signature: full-viewport landscape with a centred title; stacked full-width chapter bands with large roman
 *    numerals; article pages open with a coloured chapter cover band, continue in one narrow centred column and end
 *    with an "onward" band to the next chapter.
 * 5. Detail: a thin stepped line inspired by Shipibo-Konibo kené, used only as a border where two grounds meet,
 *    never as decoration on its own.
